This study examined the effects of support systems and traditional value beliefs about the role of women on the parenting stress of dual-career mothers. The subjects were 203 employed mothers with one child 4- to 36-months of age. The influential independent variables affecting parenting stress listed in order of significance were satisfaction with child care, value placed on traditional maternal roles, sex of child, and cost of child care. Contrary to the researchers assumptions, social support systems had no effect on parenting stress. The results of this study have implications for formal and informal support systems for employed mothers with young children.

Uniform is the dress of distinctive design or fashion worn by members of a particular group or serving as a means of identification. The postman's uniform of Ministry of Communication should be distinctive or characteristic clothing to provide high functionality and symbolization of job characteristics, cost effectiveness and esthetic. In order to design the postman's new uniform available in 2000, there has been a satisfaction survey to 1,116 postmen. A thorough analysis of survey and informal and face-to-face discussion with postmen give the direction of design concept. One of the most important things in the design concept is to make the uniform high quality & refinement. The style is a refined jumper suit in consideration of form stability, wearing satisfaction, convenience in activity. The basic colors selected are navy and medium gray. The colors of jumper are MOC red ; C.I color Green : a representative color of youth, white : a symbolic color of bright future. All three colors are plaid on a basic nary color. In the selection of the textile, synthetic fiber (Polyester 65%, rayon 35%) equipped with UV cutting as well as water resistance etc. was recommended. In the uniform design process, the effective communication with user (postman) is critical to find the requirements and needs of uniform user (postman). Also. the uniform designer should reflect the above four key factors in design development. Therefore, the uniform should provide the user with high job performance and job pride in wearing the uniform.

This study was conducted to identify the health care utilization, health care costs, and potential health care demands of the disabled in the Medicaid Aid beneficiaries. This study focused on the heath care costs not included in the medical aid allowance such as transportation, informal nursing costs, and ambulatory aids etc. Participants were the 864 subjects who were beneficiaries of the National Medical Aid program living in 10 district of Korea. A questionnaires were distributed to the disabled in the Medical Aid beneficiaries during August to September, 2001 through public offices. Data were collected through a home visiting by social workers working in public offices. Direct and indirect medical costs expended for one month by the participating disabled were examined. They expended 110.748 won $({\$}100)$ for heath care costs, which was not included in the medical aid allowance during the month. The disabled with cerebral diseases or who have level 4 disability expended more health care costs compare to those with other diseases. Gradual expansion of medical aid allowance for the disabled is recommended to alleviate economic burden of the disabled and their family.

The bilinear pairing, also known as Weil pairing or Tate pairing, is widely used in cryptography and its properties help to construct cryptographic schemes for different applications in which the security of the transmitted data is a major concern. In remote login authentication schemes, there are two major requirements: i) proving the identity of a user and the server for legitimacy without exposing their private keys and ii) freedom for a user to choose and change his password (private key) efficiently. Most of the existing methods based on the bilinear property have some security breaches due to the lack of features and the design issues. In this paper, we develop a new scheme using the bilinear property of an elliptic point and the biometric characteristics. Our method provides many features along with three major goals. a) Checking the correctness of the password before sending the authentication message, which prevents the wastage of communication cost; b) Efficient password change phase in which the user is asked to give a new password after checking the correctness of the current password without involving the server; c) User anonymity - enforcing the suitability of our scheme for applications in which a user does not want to disclose his identity. We use BAN logic to ensure the mutual authentication and session key agreement properties. The paper provides informal security analysis to illustrate that our scheme resists all the security attacks. Furthermore, we use the AVISPA tool for formal security verification of our scheme.

This study evaluated the impact of an AI heifer calf rearing scheme on dairy stock development, in a coconut grazing and a peri-urban smallholder dairy production system in the Western Province of Sri Lanka. The heifer rearing scheme included free advice on calf rearing, drugs, acaricides, minerals and subsidised concentrates for 30 months. The farmers in the coconut growing area integrate dairying with their plantation, they sell their milk to the main processors. The peri-urban farmers are intensive milk producers, who sell their milk at informal markets. To estimate the effect of the heifer rearing scheme on dairy replacement stock development, scheme farmers were compared with farmers who did not participate in the scheme. Calf mortality was twice as high in non-scheme farms (23-28%) as in scheme farms (12-14%). The scheme had a positive effect on weight development and scheme heifers calved 4.5 months earlier than non-scheme heifers. The calf rearing package is cost effective in both farming systems, however, the required cash inputs are a major constraint. The costs per in-calf heifer under the scheme are much lower than the production of such animals by either multiplication in state farms or importing them. The coconut grazing system showed the highest potential for producing surplus dairy stock.

This study analyse interorganizational networks of the self-supporting service organizations using data on the 31 organizations in Chanju area. Interorganizational networks are operationalized in two ways: conference network and referral network. First, this study attempt to examine the characteristics of interorganizational networks of the self-supporting service organizations. Using block model, I can capture some of the structural features of interorganizational networks. Major findings of block modeling are as follows: (1) Public organizations are more inactive to make a connect with other organizations. (2) Most of organizations incline to make a connect with same kind organizations. Namely, employment service organizations incline to flock together, and social welfare organizations are also much the same. Second, this study attempt to examine the determinants of interorganizational networks of the self-supporting service organizations. Relations between pairs of organizations are modeled as a function of dyadic level covariates in accordance with resource dependence, transaction cost, and organizational domain theory. Measure of informal ties between organizations are also included as covariates. Applying logit and tobit regression methods, this study reveals that most variables have effects on the dyadic relations of organizations. Through this empirical analysis, I can suggest policy implications for the self-supporting programs in Korea.

Despite the continuous efforts of academic libraries to develop various user-centered outreach programs, services and new processes, library anxiety still remains a threat to university students' full use of academic library resources. Meanwhile, a new generation of students, called the "Net Generation," has grown up with developed information and communication technology enter university and must be persuaded to turn to the library. To serve this new group of patrons better, libraries need to adopt new technologies. However, since an initial introduction cost and labor efforts are involved in the integration of the technology, identifying the right time for introduction and the right scope of innovation is essential but difficult. The study proposes a not-yet-well-known, novel experimental design, Regression Point Displacement (RPD), to evaluate an orientation program applying Mobile Augmented Reality (MAR) for STEM students. Since this RPD design requires only one treatment group, the model is expected to be the incomparable and rational way to evaluate the new MAR technology. In the context of an informal learning experience, the findings of the study will determine the effectiveness of an orientation employing the MAR technology.

This study examined the perception of farmers who employ foreign workers. A survey was conducted on 110 farms, and the main research results are as follows. First, as many farmers hire foreign workers in informal ways other than the employment permit system or seasonal worker programs, it is important to increase the number of registered foreign workers through the employment permit system or seasonal worker programs. Second, it is important to improve farmers' perception of compliance with the minimum wage, as some farmers pay wages below the legal minimum wage. Third, the subjective productivity evaluation results of farmers showed that the difference in labor productivity between foreigners and foreigners was not significant. This means that hiring foreign workers is due to other factors such as ease of management and cost rather than productivity. Fourth, many farmers were willing to hire existing foreign workers even if they paid extra wages after the expiration of the employment permit system. Finally, promotion and improvement of the additional system for foreign workers' workplaces are needed to solve problems caused by foreign employment during off-farming season.

Though a variety of demands for an green dwelling, it is hard to diffuse a wooden house due to high construction cost. So this study aims to diffuse to propose a space modular for production and supply. Therefore the result of investigation to the space modular of each room through the survey of width and depth in the type of dwelling in korea is as follows. 1) Investigated the mixture of magnitude on the total width and depth, the survey is showed commonly 3.6m and 4.2m. 2) Once the depth is 3.6m, a living room and inner room, room's width is 3.9m, 4.5m. Once the depth is 4.2m, those width is 4.8m. 3) By use of a survey, the post distances consisted of all rooms are 3.6m, 3.9m, 4.2m, 4.5m, 4.8m. The result of investigation to possibility for mixture applied to six level types invested post modules to the wooden house of post & Beam method is as follows. 1) With the regularity of depth and simplicity of width, It is potential to compound floor plan in korea. 2) It is possible to plan an informal shape of kitchen+dining room which is a spare space available for the merit changeable space after arranged main rooms. 3) It is possible to plan a space through a variety of mixture method at bathroom. Thus, it is possible for a variety of floor formations to build a low-cost wooden house through five types of post distance.

Our country has become an aging society with unparalleled speed, compared to other advanced countries. Many of the elderly are physically, economically, and psychologically dependent; this dependence is a factor that increases the cost burden not only on the children and relatives of the elderly, but also at the social level. Under the prevailing environment of the family-oriented informal support system, the burden of support for elderly parents who rely on limited resources is highly likely to lead to abuse. Until now, dealing with the abuse of senior citizens has been mostly a one-off approach through media rather than academics. Therefore, this study attempts to take an objective approach to the elder abuse problem (which has so far been dealt with in the media as a form of domestic violence) in order to grasp the specificity and factors of elder abuse and to present the Korean situation with regard to elder abuse. In addition, this study seeks to find ways to prevent elder abuse in formal and informal ways.
